Title:
VISION CARE INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2014/117753
Kind Code:
A1
Abstract:
A vision care instrument comprising a device external housing (10a) for keeping out external light, an optical convex lens assembly (12), a linear optical marker group (11a) that displays from front to back an optical marker, an annular optical marker group (11b) that displays in an annular fashion an optical marker, and a control unit for controlling the movement of an optical marker along said linear optical marker group (11a) and said annular optical marker group (11b). In the vision care instrument, the proper convex lens specifications and an accurate optical marker distance are selected and applied, and display effects are provided at near distances or from points ranging from near to infinitely far away distances. The linear optical marker group (11a) of the vision care instrument provides for changes of display from near to far, thereby allowing the ciliary muscle to contract and relax; the annular optical marker group (11b) prompts the eyeballs to move in an up-down-left-right annular fashion, forcing the six extraocular muscles to move in coordination, and thereby enabling all the muscles of the eyes to be fully active. If the distance is a negative number, the display position and the optical marker are positioned on the left.
